Infos

This volume outlines and examines current understanding of botulinum toxin and its various therapeutic applications. It presents therapeutic uses across a variety of medical subspecialties and patient populations. Each chapter focuses on a particular symptom and explains how botulinum toxin is currently used for treatment. Coverage also examines questions of immunity and explores economic issues. Written by leaders in their fields respected for their progressive approach to treatment, the book encourages responsible research into new and novel uses of botulinum toxin.

---

Justinius Kerner, a German medical officer and poet, was the first to realize that botulinum toxin potentially might be useful for therapeutic purposes. Kerner made this observation in 1822, but he did not call the toxin "e;botulinum toxin. "e; Instead, Kerner called it the substance in "e;wirkenden stoffes,"e; which translates to "e;bad sausages. "e; Kerner realized that there was a "e;fat poison"e; or "e;fatty acid"e; within sausages that produced the toxic effects that we now know as botulism. Nearly a century would pass before the bacterium producing the toxin would be isolated and the toxin ultimately renamed "e;botulinum toxin. "e; As farsighted as Kerner was, it is doubtful that even he could have predicted just how much potential therapeutic punch was packed within his wirkenden stoffes. It was not until 1978, more than a century and a half after Kerner's prediction, that Dr. Allan Scott received Food and Drug Administration approval to test botulinum toxin type A in human volunteers. We do not yet have a comprehensive understanding of precisely how botulinum toxin works in the human body or how our bodies fully respond to the toxin. We do know that it temporarily paralyzes muscle by inhibiting the release of acetylcholine, and it also appears to inhibit the release of other neurotransmitters.
